Substantially, in order to induce the objects, the blade assembly 120 needs to have an appropriate and a profile or contour.
- the blade assembly 120 in FIGS. 5A and 5B [10-6] includes a first assembly 120 a and a second assembly 120 b connected with each other.

A cyclone mechanism or a filtering device may be applied to the collectingdevice 21 so as to separate the dust and other objects from the air. - The
coupling pipe 30 includes anextension pipe 31 connected to thesuction nozzle 10, acoupling hose 32 made of a soft material and connected respectively to theextension pipe 31 and thebody 20, and ahandle 33 provided between theextension pipe 31 and thecoupling hose 32. - As well illustrated in
FIG. 2 including a floor that faces the surface to be cleaned, thesuction nozzle 10 includes ahousing 11, aninlet 12 formed on a floor of thehousing 11, and anagitator 100 disposed in theinlet 12. Thehousing 11 includes a predetermined space therein, and a passage is disposed in the space so as to guide the air sucked in from theinlet 12 to theextension pipe 31. In addition, a pair ofwheels 11 a is rotatably provided at a bottom member of thehousing 11 so as to easily move thesuction nozzle 10. Theinlet 12 is extended on both sides of the bottom member as illustrated. - The
agitator 100 rotates and sucks in dust and other objects on the surface to be cleaned, together with the air. In the present invention, theagitator 100 includes abody 100, and at least oneblade assembly 120 mounted at thebody 100. Theagitator 100 will be described in more detail with reference toFIG. 2 and the following drawings. - First of all, the
body 100 is rotatably mounted at theinlet 12 and formed in a cylindrical form so as to be smoothly rotated. Thebody 100 may be freely rotated between theblade assembly 120 and the surface to be cleaned. In other words, as illustrated inFIG. 2 , when the suction nozzle 1 moves in an arrow direction, frictional force is applied to thebody 110 in an opposite direction of the arrow direction so as to rotate thebody 110. Since a rotation direction of thebody 100 is changed according to a forward direction and a backward direction of thesuction nozzle 10, efficiency of theagitator 100 may be changed according to a moving direction of thesuction nozzle 10. On the other hand, the body may be rotated by an additional driving mechanism. The driving mechanism includes an impeller (not shown) mounted in thehousing 11, and a belt (not shown) coupled with the impeller and thebody 110. Accordingly, the impeller as well as thebody 110 connected by a belt is rotated by the air sucked in. Since the driving mechanism enables to continuously rotate thebody 110 in a predetermined direction, it is desirable that predetermined efficiency of the agitator is secured. Theblade assembly 120 plays a role of separating dust and other objects from the surface to be cleaned such that the dust and other objects are sucked in through the inlet 12 [8-3]. In order to improve cleaning efficiency of the vacuum cleaner, a plurality ofblade assembly 120 is mounted at thebody 110. As illustrated inFIGS. 3A and 3B taken along the line I-I ofFIG. 2 , theblade assembly 120 includes a plurality ofblades 121 and extended from thebody 110 in a length direction thereof. Each of the plurality of theblades 121 is configured to come in contact with the surface to be cleaned. Accordingly, each of the plurality of theblades 121 is made of a soft material and has a body that is continuous and solid. Accordingly, contrary to a conventional brush, theblades 121 uniformly come into contact with the surface to be cleaned, thereby wiping out the almost entire surface when thebody 110 is rotated. Therefore, each of the plurality of theblades 121 separates almost all objects from the surface and then suck in through theinlet 12. - When the
blade assembly 120 includes only one blade formed in a continuous form, thebody 110 may not be smoothly rotated because of excessive friction against the surface to be cleaned. Accordingly, theblade assembly 120 includes a plurality ofblades 121, and the plurality ofblades 121 are spaced for a predetermined space. - When the
blades 121 are overlapped each other, great friction is caused against the surface in the same way. Therefore, theblades 121 are serially disposed along thebody 110. As illustrated inFIG. 4A , the blades may generally have square sections. In order to reduce the friction against the surface, it is advantageous that each end of theblades 121 being in contact with the surface has a reduced section so as to decrease the friction against the surface. - In other words, the
blades 121 have a trapezoid section as illustrated inFIG. 4B , or a triangle section as illustrated inFIG. 4C . Theblades 121 may smoothly rotate thebody 110 under a substantially small friction. Theblades 121 are more flexibly made such that the reduced sections come in uniform contact with the surface. - As illustrated in
FIG. 3A , theblade assembly 120 may includeonly blades 121 which are independent and separable. It however requires a long time and complicated work to install theblades 121 to thebody 110. Accordingly, it is desirable that theblades 121 be coupled with each other so as to be easily mounted at thebody 110 as illustrated inFIG. 3B . In more detail, theblade assembly 120 includes astrip member 122 connecting theblades 121 with one another. In other words, theblades 121 are formed as one body by thestrip member 122. Shapes of a free end and a middle portion of each of theblades 121 may be changed to a certain degree so as to come into contact with the surface to be cleaned. Accordingly, thestrip member 122 connects supporting ends, that is, ends of theblades 121 mounted at thebody 110 so as to allow the shape change. Thestrip member 122 may be mounted on a surface of thebody 110, but desirably inserted into thebody 110 as illustrated in the drawing. When theblade assembly 120 includes only theblades 121, theblades 121 are mounted on the surface of thebody 110 or in thebody 110. - Besides, suction forces are different according to parts of the
inlet 12. Accordingly, in order to suck in the dust and other objects larger than dust better, it is desirable that theblade assembly 120 induce the objects to a place of the inlet, with a strong suction force. Substantially, in order to induce the objects, theblade assembly 120 needs to have an appropriate and a profile or contour. - The profiles of the assembly are illustrated in
FIGS. 5A and 5B . To meet the convenience in describing, theblade assembly 120 inFIGS. 5A and 5B [10-6] includes afirst assembly 120 a and asecond assembly 120 b connected with each other. - As illustrated in
FIGS. 5A and 5B , thefirst assembly 120 a and thesecond assembly 120 b are sloped and extended respectively from both sides of thebody 110 toward a central axis (C) of thebody 110. The first andsecond assemblies predetermined point 120 c. Alternatively, the first andsecond assemblies body 110 so as to be connected with each other at thepoint 120 c. On the other hand, theblade assembly 120 illustrated in the drawings may be regarded as including a predetermined conversion member 120C converged on the center portion from the both ends of thebody 110. Similarly, theblade assembly 120 illustrated in the drawings may also be regarded as disposed on thebody 110 so as to have arecess portion 120 c. All the aspects mentioned above considered, when the first andsecond assemblies FIG. 5A , theblade assembly 120 is disposed simply in a “V” shape. When the first andsecond blades FIG. 5B , theblade assembly 120 is disposed in a “U” shape. Due to the curvature, theblade assembly 120 enables to smoothly induce and gather the objects on the surface to be cleaned without large friction. - Substantially, the suction force of the
inlet 12 is strongest at the center portion thereof and the first andsecond assemblies body 120 corresponding to the center portion of theinlet 12. In other words, thepoint 120 c is located at the center portion of theinlet 12, and similarly the conversion member or therecess member 120 c is located at the center of theinlet 12. Accordingly, when theblade assembly 120 is rotated along with thebody 110 in the arrow direction, the objects on the surface is induced to the center portion of theinlet 12 by the first andsecond assemblies first assembly 120 a and thesecond assembly 120 b are joined, that is, the center of theinlet 12. - Thereafter, the objects gathered to the point are sucked into the center portion of the
inlet 12 by the strong suction force of theinlet 12. In other words, theblade assembly 120 of the present invention is configured to guide and gather the objects to the center of theinlet 12 with the strong suction force such that the objects are sucked in well. - [11-20] When the first and
second assemblies body 110 in a direction same as the rotation direction and as illustrated as a dotted line inFIGS. 5A and 5B , the objects on the surface to be cleaned are guided to ends of theinlet 12 along the first andsecond assemblies inlet 12. Therefore, it is desirable that theblade assembly 120 is extended from the both ends of thebody 110 toward the center portion thereof in an opposite direction to the rotation direction of thebody 110. - When the first and
second assemblies body 110, the joiningpoint 120 c, i.e., the conversion member and the recess member, is ahead of the both ends of theblade assembly 120 as illustrated as the dotted line. Accordingly, with the same reason, it is desirable that the joiningpoint 120 c (the conversion member and the recess member) follows the both ends of theblade assembly 120 in the rotation direction of thebody 110. - Meanwhile, the
blade assembly 120 may be directly adhered to the surface of thebody 110 or inserted into thebody 110 so as to be firmly coupled thereto. For this reason, thebody 110 includes agroove 111 for partially accommodating theblade assembly 120. - It is desirable that the
groove 111 be configured to be geared with theblade assembly 120 so as to be firmly geared with theblade assembly 120. In more detail, as illustrated inFIG. 6A , thegroove 111 includes at least one projecting member 111 a extended inwardly from the inlet of thegroove 111, and the coupledblade assembly 120 is latched on the projecting member 111 a. As illustrated inFIG. 6B , thegroove 111 has a section gradually reduced from a bottom member to an entrance thereof [12-20]. In other words, thegroove 111 has a side wall, that is, ataper member 111 b, and theblade assembly 120 is latched on thetaper member 111 b. Consequently, thegroove 111 illustrated inFIGS. 6A and 6B has a reduced section at the entrance thereof so as to be geared with theblade assembly 120. Therefore, theblade assembly 120 is firmly coupled with thebody 120 without coming out therefrom. - In the same manner, the
blade assembly 120 is configured to be tightly fitted in thegroove 111. In order to be tightly fitted in thegroove 111, a part of theblade assembly 120, i.e., a section of the support end is has the same shape as the section of thegroove 111. II more detail, the as illustrated inFIG. 7A , theblade assembly 120 may include at least one projectingmember 122 a caught by the projecting member 111 a of thegroove 111 illustrated inFIG. 6A . As illustrated inFIG. 7B , the blade assembly may also include a taperingmember 122 b so as to be fitted in thegroove 111. The projectingmember 122 a and the taperingmember 122 b are shown as to be formed at thestrip member 122. When theblade assembly 120 includes only theblade 121 without thestrip member 122 as illustrated inFIG. 3A , theprojection member 122 a and the taperingmember 122 b are formed respectively at theblade 121. - As mentioned above, when the
groove 111 is formed as illustrated inFIGS. 6A and 6B , theblade assembly 120 may be firmly coupled with thebody 110 without using glue or a fixing member. With the same reason, theblade assembly 120 may be laterally inserted from an end of thebody 110. In this case, in order to laterally insert theblade assembly 120, thegroove 111 needs to be passed through one end of thebody 111 as illustrated as “A.” Accordingly, theblade assembly 120 is firmly and easily coupled with thebody 110. - It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
- In the agitator of the present invention mentioned above, a blade assembly includes a plurality of blades. Accordingly, an entire surface to be cleaned is uniformly wiped out. The blade assembly is separable from the surface to be cleaned such that all the objects can be sucked into the suction nozzle. The blade assembly also includes an optimum profile so as to guide and to gather the objects to a particular point of the inlet with a strong suction force. Accordingly, almost all objects are sucked into the suction nozzle. Therefore, efficiency of the vacuum cleaner is largely improved by the agitator of the present invention.
